# How do you reverse the direction of a DC motor in Arduino?

Contents

To control the direction of the motor, the pins in1 and in2 must be set to opposite values. If in1 is HIGH and in2 is LOW, the motor will spin one way, if on the other hand in1 is LOW and in2 HIGH then the motor will spin in the opposite direction.

## How do you control the direction of a DC motor?

If you switch the leads, the motor will rotate in the opposite direction. To control the direction of the spin of DC motor, without changing the way that the leads are connected, you can use a circuit called an H-Bridge. An H bridge is an electronic circuit that can drive the motor in both directions.

## How do you make a motor move forward and backward?

Remove power from the motor. Hook the battery positive wire to the negative terminal and hook the battery negative wire to the positive terminal for a simple DC motor. Install a double pole double throw changeover switch between the battery and the motor. The motor will now have a forward, reverse and an off position.

## How does Arduino change speed of dc motor?

The EN A pin of IC is connected to the PWM pin 2 of Arduino. This will control the speed of the motor. To set the values of Arduino pins 8 and 9, we have used the digitalWrite() function, and to set the value of pin 2, we have to use the analogWrite() function.

## How do you reverse the direction of rotation of a motor?

The direction of rotation of a dc motor can be reversed:

1. By reversing the connections of both armature and the field windings with the supply.
2. By reducing the field flux.
3. By reversing the connections of either the armature or the field winding connection with the supply.

## What is PWM in Arduino?

Pulse Width Modulation, or PWM, is a technique for getting analog results with digital means. Digital control is used to create a square wave, a signal switched between on and off. … In other words, with Arduino’s PWM frequency at about 500Hz, the green lines would measure 2 milliseconds each.

## How does Arduino DC motor connect to L293D?

Connect Vcc1 pin to 5V output on Arduino. Make sure you common all the grounds in the circuit. Now, the input and enable pins(ENA, IN1, IN2, IN3, IN4 and ENB) of the L293D IC are connected to six Arduino digital output pins(9, 8, 7, 5, 4 and 3). Note that the Arduino output pins 9 and 3 are both PWM-enabled.

## How do you rotate a DC motor in both directions?

Fixing rotation problems for DC motors

DC motors, like AC motors, can be configured to turn in either direction. Their direction can be easily controlled by inverting the polarity of the applied armature voltage by reversing the armature leads. This works with shunt, series, and compound wound DC motors.

## How do you control the speed and direction of a DC motor?

Thus, the speed of a DC motor can be controlled in three ways:

1. By varying the supply voltage.
2. By varying the flux, and by varying the current through the field winding.
3. By varying the armature voltage, and by varying the armature resistance.

## Are DC motors reversible?

Simply put, DC motors can turn in either direction (clockwise or counter-clockwise) and can be easily controlled by inverting the polarity of the applied voltage. Strictly speaking, the motors can actually create a force in either direction.
